Lol, I'm just over a week in to learning NixOS and this feels so true 😂

I feel like I'm just starting on the incline, luckily I don't have any sturdy rope on hand 😂

Wait what, why? I'm out of the loop. What's up with Proxmox and glib 2.0?

Reading your post again, you should start by moving your docker management from CasaOS to vanilla docker-compose files, and keep them in a git repo.

I still think you definitely should look in to NixOS and what it can offer, cause it seems like that is where your mindset is going.

But NixOS is a drastic change, you should start by just converting your individual services one by one from CasaOS management to docker-compose files. One compose file for all services is possible, but I would recommend one compose file for each service. Later you can move from Debian to NixOS while using the same docker-compose files.

I would like to have a system when I know what I did, what is opened/installed/activated and what is not

You sound like you need to to look in to Nix and NixOS. The TLDR is that everything is declared in a configuration file(s), which you can and should back up in git. The config files tell you exactly what you did , and the config file comments together with git commit history tell you why.

The whole system is built from this configuration file. Rollback is trivially easy, either by rebooting and selecting an older build during the boot manager, or reverting to an older git commit and rebuilding (no reboot required, so usually faster)

Now fair warning, Nix (and NixOS) is a big topic, very different from normal way of thinking about software distribution and OS. Nix is not for everyone.

You should also at the very least have a git repo for docker-compose files for your services. Again, that will declaratively tell you what you did and why.

Also, if NixOS is too extreme, you should also look in to declarative management tools like Ansible etc

No and kinda yes. Duckduckgo has its own webcrawler, but also adds in results from other sources including Bing, Yahoo and others.

Yes this! They sell HomeAssistant Green for 100$ and HomeAssistant Yellow does ship from various European sellers at various prices.

Otherwise agreed a used 1liter PC from a local IT refurbisher the best option if buying a general PC for HA.

Oh cool, 4x 2.5G ethernet for €200! These could make an awesome pfSense / openSense router.

I've seen similar boxes on AliExpress etc , but there you never know what you're getting, with model numbers and "manufacturers" all over the place. And forget about any form of support.

Edit: somehow forgot that HA sell their own devices, HomeAssistant Green for 100$ and HomeAssistant Yellow which also supports the project.

Original comment: Highly recommend a used "enterprise mini PC" from Dell , HP or Lenovo. Get it from your local IT refurbisher, eBay or your local ebay-equivelent.
These are sometimes called 1L PCs for their 1 Litre size. Model names are Dell Optiplex, HP Elite desk or Prodesk, Lenovo Think centre. Prices are €100 to €1500 depending on age and specs. €150 should be more than enough for HomeAssistant.

Alternatively https://slimbook.com/en/ sells Linux PCs out of Spain, and https://www.tuxedocomputers.com/ out of Germany.

Another option is the british RaspberryPi, but that might be more hassle. You need to separately get a good power supply and cable, good SD-Card, case, maybe with fan. And its ARM not x86, but that doesn't matter for HomeAssistant unless you're doing something very exotic.

Am I looking in to a mirror?

Not a problem when self-hosting on own hardware. Especially in winter. Overly complicated spaceheater goes brrrr

AntennaPod. Free, open source and just works perfectly, fast and snappy, unobtrusive. This is the way.

Another alternative is PodVerse. Also free and open source. More features, but more sluggish

Today I Learned, thanks for sharing.

From your linked thread it seems potentially still acceptable, being fully local , open source, and with an international contributor team. But yeah no such ties with LibreOffice.
